5x/6x/7x/8x/9x Survivors Crashlanding Scenario

Allows you to start with up to 10 survivors in the Crashlanding scenario. You wont need the big family rule as it is possible to get your maximum survivors up to 12 à 20 survivors through events, but they can also die in events. Also according difficult there some extra resources to start building a survival camp. Start the game at 4h a.m and 2 days earlier then regular scenario. To solve the issue with no happiness at start of a scenario I added a Chocolate Bar that when survivors eat it they get instant 80% happiness, this resource isn't craftable and only purpose is so survivors don't break down, so when landed first need to do is eat such a candy bar. Added all the Crashlanding related story bits.
